    Puts out an unbelievable amount of light for such a small light compared to other lights of similar capabilities. Very well thought out on design and function. Very reasonable price for what you get. I would highly recommend this product.

    will it take 4123A batteries?

      The LR35R uses two 21700 rechargeable li-ion batteries. Two CR123A would be the same size as an 18650 battery, which is smaller than the 21700 in this light. So 4 CR123A will not be the same size as two 21700.

    Having this light in my life for 20 days now I can honestly say WOW! I didn’t completely know what to expect getting a 10,000-lumen light, but during the unboxing I was completely amazed with how much power was clearly packed into such a compact light. The weight of the light caught me off guard, over the years I have carried multiple brands of lights, but they always seemed extremely bulks and hard to keep in keep on hand for any period. This light fits perfect in hand, its not overly bulky and the carrying pouch that comes with it is easily useable. I currently keep this light on my to go bag at all points in time and it fits my everyday life style perfectly.
    When it comes to the light itself, the metal body makes you know that you have a sturdy product in hand so soon as you pull it out of the box. When turning on the light for the first time I was dumbfounded with how bright it was. I was sitting at my kitchen table, with the windows open during the middle of the day, and at 10,000 lumen this made my room brighter. Knowing that this was as powerful as it was, I knew I had to take the time to try it out at night. So, on recent coyote hunt I brought this along as our tracking light. When we used this for tracking in a pitch-black field around Mid Night, I found that this light literally makes the night turn day.
    Overall, from a quality, durability, and over all great light stand point this is bar none a light that I am glad I added to my collection. Being able to see the quality of this thing it has truly made me a believer in these lights. Not all things are created equal, and this light is proof of it.

    What a powerhouse! I was in love with my TK35 and thought it was the greatest thing ever, then the TK35UE came along, and that was the greatest ever. I’ve tried many other flashlights, but I’ve always appreciated the dual-battery, compact size of the TK35. Now the LR35R comes along with a much more powerful output in a significantly smaller package, and we have a winner.

    The USB-C external charging port is great, I love that I don’t have to take the flashlight apart and remove the batteries to charge them.

    The power button is located on the side of the unit, which is not my preference. It’s much faster and more intuitive to be able to find an on/off button that located on the tailpiece, so I’m a bit disappointed in that.

    Like all Fenix flashlights, it’s built like a tank. It’s significantly shorter than the TK35, which is convenient. It looks like this was achieved by putting a bunch of LEDs at the front of the lens with very small reflectors instead of having a single LED with a huge recessed reflector. This makes for a wide, even light.

    And of course, at 10,000 lumens, this light is insanely bright. I’ve included comparison images between the LR35R, TK35UE (3200 lumens), and the TK35 (860 lumens) below. All of the flashlights are set to full brightness. It’s pretty insane. The downside is that it gets hot quite quickly.

    If you need a search light that is durable and weighs practically nothing then spend the money and purchase this one. As a person who has spent 21 years in law enforcement carrying the big D cell flashlights this should be the new “standard department issued” light for search and rescue. Remember to bring 2 extra sets of batteries for long nights.

      Please note we recommend using Turbo mode for a short time due to the heat that is produced in this mode.

    Why does the casing run so hot at Turbo mode? I wished the casing had a way to divert the heat away from where your hands is in contact with the handle.

    Second review of the lr35r. The fellow in warranty with Fenix promptly sent me out a second flashlight as I broke the rubber cover off the first flashlight. I Appreciate your quick response. My first and my second lr35r did not come with a wall charger. Therefore, I used a couple of different Chargers on both my first and my second LR 35r. Both flashlights had an intermittent flashing red and green signal while charging and never would show it reached a full charge with the two various wall Chargers I used. One of the wall Chargers was from Fenix that came with another light I ordered from them. I considered sending second light back because I assume there might possibly be something wrong with the internal Electronics because the phone was not charging properly. I like the light and I wanted to keep it so I ordered a wall charger from Amazon. When I used the wall charger from amazon the flashlight charged properly to a complete charge as per the instructions. I’ll try to add a link in here on the charger that I ordered. My comment or advice to Fenix, you need to be on your A-game. I pay this much for a flashlight I wanted it to work when I receive it. The internal Electronics is obviously pretty sensitive and you need to have the proper charger to charge this light. Include a proper charger so the light functions properly because I have a lot of choices where I make my purchases. I recommend this light but you need to get on your A game Fenix.

      Hi Rob – please note that we do not include the wall charger with any lights. The rechargeable lights include the appropriate charging cord but they do not include the USB wall charger. We have learned through our own testing that the LR35R must have a wall charger of at least 2 AMPS.

    Fits well in the hand, awesome size with this much power.Awesome torch that throws off some heat.

    I have the bigger brother (LR40R) flashlight from Fenix. The new LR35R is almost just as bright but makes up for it in size. I can carry the new LR35R in my pocket, although I am 6’3, 245 lbs. Your mileage may vary depending on your size. It conceals pretty good in the front pocket of my 5.11 jeans. A few things I like about it; brightness/size, weight, modes, button position, tail stand, easy to charge, pocket clip, etc. Not really any knocks but if you told me I had to list one, I’d do without the charge port cover as they tend to get stretched over time when using it over and over to charge the battery. It’s still waterproof without the cover but I’d rather just remove the batteries and charge them in a standalone charger. But, that’s me. Everyone has their own preferences. I will say, I would like to see Fenix use the external charging system like they use on the E18R. No ports, just a magnetic charge cable. Some intended uses I plan for it are for camping, hiking, and general use around the house. The battery lasts a very long time on the first couple of modes. Highly recommended.

    I just received my lr35r last night. Today I’ve already broken the rubber cover off of the type C charging port. Nice flashlight, very bright, but the rubber that holds the charging port cover on is very small and did not take much to pull it completely off.
    I have several Fenix flashlights and some gun mounted and have never had an issue. This charging port is not very strong. One other suggestion. The USB charging cable should be just a little bit longer.

    Just received this light today after pre-ordering. It is by far the brightest flashlight I have ever seen. The turbo mode at 10,000 lumens is incredible. With that much output comes lots of heat though. I suggest wearing gloves if you plan on using the turbo mode because this light does get pretty hot after a few minutes.
